Terrence buys a new car for $20,000. the value of the car depreciates by 15% each year. if f(x) represents the value of the car after x years, which function represents the car's value? f(x) = 20,000(0.85)* f(x) = 20,000(0.15)* f(x) = 20,000(1.15) f(x) = 20,000(1.85)

Step-by-step explanation:

We know that the exponential decay (depreciation) equation with rate of decay r in time period x is given by :-

, A is the initial value .

Given: The initial value of truck = $20,000

Rate of depreciation= 15% = 0.15

Now, the function represents the car's value after x years is given by ;-

what grade level is this? need to know so i can look in my old textbooks!
